MOSAIC VENEER.

Speccation forming part of Letters Patent No. 28,481, dated May 29,1860;Reissued June 4, 186'?, No. 2,633.

To all whom it may concern:

Be it known that we, OTTo HEINIGKE and MORITZ LAEMMEL, of Bay Ridge, inthe county of Kings and State of New York, have invented a. new andImproved Method. of Producing Mosaic Veneers; and we do hereby declarethat the following is a full, clear, and eXact description thereof,reference being had to the accompanying drawings, forming a part of thisspecification, in which Figure l is a perspective view of the apparatus,which we use for forming the strips from which our mosaic veneers aremade. Fig. 2 is a similar' view of the apparatus, used for dividing thecomposition used for the veneer. Fig. 3 is a perspective view of one ofour blocks, when ready to be cut up and to be formed in veneers.

Similar letters of reference indicate cor responding parts in bothfigures.

Our invention consists in a particular method of producing mosaicveneers from strips of a triangular, square, pentagonal,

' hexagonal, or oct-agonal, or any other desir able cross-section, ofvarious colors, formed by pressing a plastic material, which will hardenafter having gone through the whole process, through openings of therequired shape, said strips being cut up in a large number of smallcubes or prisms which are fastened down on a piece of wood according toa certain pattern; and ou'r invention con sists also in uniting thestrips formed as above described into blocks, a cross-section of whichrepresents the pattern to be represented by the mosaic veneer or aportion of the same, so that by cutting up said blocks into thin plates,a large number of veneers of the same pattern are obtained by oneoperation.

To enable those skilled in the art to make and use our invention we willproceed to describe it with reference to the drawing.

7e take some plastic material, capable of being colored in variousshades, and which will become hard after it has gone through the wholeprocess and divide it into a number of parts, equal to the number of thecolors contained in the pattern which is to be imitated.

Each color is now forced through a metal plate containing one or moresmall apertures whereby the plastic mass is divided into long thinstrips. The apertures in the metal plate, give to thestrips the requiredform, and by using an apparatus such as shown in Figv l, a .numberioftheseistrips and` 0f diff renent colors may be formed at the same time.This apparatus contains a block A, with a large number of cylindricalopenings, a, (see Fig. 2) to receive the plungers b, and a perforatedmet-al plate B, is firmly secured to the under side of the block A. Theperforations in the plate B, correspond in shape, to the shape of theseveral colors in the pattern to be copied, and each of the openings a,is filled with a quantity of the plastic material of the desired color.For lling the openings a, we use a device, such as represented in Fig.2, consisting of a cylindrical vessel C, with a ointed mouth piece c atthe bottom. A piston D, is moved up and down in the interior of thevessel C, by means of a lever E. The mouth piece c, is broughtsuccessively over the openings contained in the block A, and bydepressing the piston D, the material contained in the cylindricalvessel C, is forced out into the openings a. Several vessels C, are kepton hand, and each one is filled with a different color, so that theopenings in the block A, can be filled with the proper colors in an easymanner. After all the openings a., have been filled, the block A, isbrought under the plungers Z), and bydepressing these plungers, the masscontained in said openings is forced out through the perforations in theplate B, forming small strips of different colors, the colors beingpreviously arranged according to the pattern to be copied. An inclinedboard F, receives the strips as they ooZe out of the plate B and whenlong enough they are separated froln the plate and pushed together bymeans of a straight edge, and they are now united by some suit ablecement. By these means, one portion after the other of the pattern isrepresented by small thin layers, each layer being formed by a number ofsaid strips. By uniting these layers, blocks G, are formed, the crosssection of which, represents the pattern to be represented, or a portionof the same, as clearly shown in Fig. 3. These blocks are now cut upcrosswise into a number of thin plates, each plate of the thickness ofan ordinary veneer, and by fastening the plates on a suitable surface inthe desired order, the pattern to be represented is faithfully copied.

By using our method, mosaic surfaces can through openingsof the requiredshape, substantially as and for the purpose described.

2. Uniting the ,strips formed as above described into blocks Gr, across-section of which represents the pattern to be represented by themosaic veneer, or a portion of the same, substantially in the manner,and for the purpose specied.
